Delfi-n3Xt: 2405 MHz Downlink Test

Delfi-n3Xt Satellite

Delfi-n3Xt Satellite

Delfi Nanosatellite Program Manager, Jasper Bouwmeester PC4JB, has announced that the team plan to activate the Delfi-n3Xt satellite’s 2405 MHz downlink on May 13-17, 2014.

Dear all,

It has been a while since you heard from us. We are still having problems to receive our satellite since our transponder test. We now want to try something different: trying to activate our S-band transmitter and let it transmit at full power for a pass. If we are able to receive a signal from the S-band, we know that Delfi-n3Xt still has an operational receiver and we could potentially demodulate the S-band signal. But since we already know that the latter is difficult, the first focus is just to “see” the signal. Since the satellite is still tumbling, it is a matter of link budget and statistics if we are able to catch the signal. To increase our chanceswe would like to ask the help of radio amateurs in the neighbourhood with suitable equipment. Since we have to actively command the satellite we have planned the passes which are suitable for the Netherlands, Germany, Belgium and Northern France and the availability of operators from our side. According to a quick survey, you are living in the area in reach at the selected passes.
The question to you:

Do you have S-band (2405 MHz) reception functionality with a dish of at least 2.5 meter and tracking capability and willing to follow and record one or more passes for us?

If so, please let us know your location, the gain of your antenna and the passes you are able to follow. Off course you do not have to be actively present during the pass. You can just record it and send the recording later through http://www.wetransfer.com.

Delfi-n3Xt will send at 2405 MHz +/- 100 kHz. The latter is the worst case uncertainty band, but I expect it to be pretty close to the right frequency. If you have an SDR, you can best set it at +/- 1 MHz around the centre frequency. Off course you do not have to be actively present during the pass. You can just record it

The planned attempts are stated by the LOCAL time of commanding below. If successful transmission would be within the 10-20 minutes after the indicated time.

– Tue 13-05 ~11.25h local time
– Wed 14-05 ~12:00h local time
– Thu 15-05 ~22:10h local time
– Fri 16-05 ~11:35h local time
– Sat 17-05 ~12:10h local time

If you are able, your help is highly appreciated!

Vy 73,
Jasper PC4JB

Future FUNcube missions – 2014 launch dates

UKube-1 on display at UK Space Conference in Glasgow

UKube-1 on display at UK Space Conference in Glasgow

The FUNcube team have received confirmation that UKube-1, which is hosting the FUNcube-2 payload, remains scheduled for a Soyuz launch on June 19. The team do not, as yet, have any lift-off times or TLE’s for this launch but we will make these available as soon as possible.

It is believed that, immediately after deployment and activation, UKube-1 will commence transmitting a CW beacon and that this will be later followed by an AX25, 1k2 BPSK beacon. Both beacons will be on 145.840 MHz. The FUNcube-2 payload, with its telemetry downlink for educational outreach, is expected to be tested later.

FUNcube-3 is the transponder only payload on the QB50 precursor CubeSat “QB50P1″. This mission is currently scheduled to launch “Not earlier than the second half of June” , on a Dnepr LV from Yasny. The initial beacon signals, from the main transceiver, are also expected to be AX25, 1k2 BPSK packets on 145.815 MHz. Again more information will be provided as soon as it becomes available.

The winning contestants will be invited to develop their ideas further with celebrity chef Heston Blumenthal, and these ideas will be turned into real space food that will be launched to the ISS. They will also be invited to an event that will include a live link up with Tim during his stay on the ISS.

Heston syas “I’m unbelievably excited to be designing a delicious meal for Tim to enjoy in space; there are some real challenges ahead, things aren’t quite the same up there! I’m really looking forward to seeing some incredible suggestions by the kids, and getting started on creating something that Tim will love up there in space.”

The challenge is open to classes, other groups (such as after-school clubs, Scouts, Guides, etc) and individuals. There are two categories, one for primary level children and one for secondary level children, with one winner in each category.

Children will need to design a British-inspired meal for Tim to eat in space, taking account of normal nutritional principles as well as the constraints of space (such as handling, packaging and preservation).

The QB50 project has reached another crucial milestone. The first two QB50 satellites have been delivered for shipment to the launch site after a successful flight acceptance test campaign. The satellites will form the QB50 Precursor mission that seeks to de-risk and validate key technologies of the QB50 main flight that will be performed in the coming years.

The launch is planned for June 19, 2014 from the Russian ICBM base at Dombarovsky near Yasny on a Dnepr rocket manufactured in Dnepropetrovsk, Ukraine. The satellites will be put into a 650 km Sun Synchronous Orbit (SSO).

The following payloads were integrated into the ISIS satellite platforms:

QB50p1
• INMS Payload from MSSL, UK
• QB50 ADCS system from SSC, UK
• Thermocouple experiment from VKI, Belgium
• AMSAT-NL 435/145 MHz linear transponder (FUNcube-3) from AMSAT-NL, The Netherlands

QB50p2
• FIPEX Payload, University of Dresden, Germany
• QB50 ADCS system from SSC, UK
• Thermocouple experiment from VKI, Belgium
• AMSAT-Fr 435/145 MHz FM voice transponder from AMSAT Francophone, France

QB50p1 (FUNcube-3) has a VHF 9600 bps BPSK telemetry downlink plus a linear U/V transponder similar to that already flying on FUNcube-1 with an output of 400 mW.
• 145.815 MHz 9600 bps BPSK telemetry beacon
• Inverting SSB/CW linear transponder 400 mW PEP
– 435.035 – 435.065 MHz Uplink LSB
– 145.935 – 145.965 MHz Downlink USB

QB50p2 has  a VHF 9600 bps BPSK telemetry downlink plus a separate RF payload from AMSAT-Francophone which will comprise of a FM voice transponder with UHF uplink and VHF downlink. It will also transmit FX25 telemetry at 9600 bps.
• 145.880 MHz 9600 bps BPSK telemetry beacon
• 145.840 MHz 9600 bps FSK FX25

QB50p CubeSats

The project was executed to an unprecedented timeline. Formal Kick-Off was in October 2013 and all hardware from the different partners was delivered for integration into the satellites in January  2014. This means that two satellites were delivered in just over 6 months. Furthermore, with a precursor launch scheduled in June, launch and operations will commence within 9 months of project Kick-Off.

This fast-track project shows how successful a close cooperation between academic institutes and experienced companies can be. With ISIS’ experienced team of engineers that design and build nanosatellites on a regular basis (ISIS remains on track to delivering 1 satellite system per month in 2014), throughput times of nanosatellite projects can be shortened significantly.

The upcoming launch of the QB50 precursor satellites will also be the first satellites to be launched that were funded through the EU’s FP7 space technology programme, in which a number of innovative small satellites will be launched in the coming years to demonstrate new European space technologies.

The lessons learned from the QB50 Precursor development and operations have already led to many recommendations to further improve and streamline the QB50 main flight. All teams involved in QB50 stand to benefit from the experiences gained over the last months.

At the beginning of March Tim gave a presentation to the UKSEDS National Student Space Conference in Leicester. During the talk he expressed his enthusiasm about getting his amateur radio licence and operating from the International Space Station (ISS).

Tim is currently training for his 6 month mission, Expedition 46/47, to the ISS which is scheduled for November 2015. The UK communications regulator Ofcom has agreed in principle to issue the permanent Special Callsign of GB1SS to the ISS and it is expected Tim will use that callsign when operating the amateur radio station in the ESA Columbus module.

The UK’s first astronaut was Helen Sharman GB1MIR who launched into space 23 years ago on May 18, 1991, see https://amsat-uk.org/about/history/first-uk-astronaut-helen-sharman-gb1mir/

The USA Technician licence is the equivalent of the UK Foundation. The 35-question Technician exam covers topics such as radio theory, regulations and operating practices. 26 of the 35 questions need to be answered correctly to pass. Unlike the system in the UK there are no practical assessments for the USA exams just a single multiple choice exam paper. All the questions and answers for the US exams are available online and you can try a practice Technician exam at http://www.qrz.com/hamtest/

Technicians are allowed to use up to 1500 watts output on all the VHF, UHF and Microwave bands and 200 watts output on four HF bands. USA Technicians have full amateur privileges in the frequencies they are allocated, for example they can do set up beacons or repeaters, operate maritime mobile and design and build their own equipment.
